【JSP开发】response输出中文和数据的问题

package cn.edu.Response;

import java.io.UnsupportedEncodingException;

import javax.servlet.ServletException;

//servlet中用OutputStream输出中文和数据的问题
public class ResponseDemo1 extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

test2(response);
}

private void test1(HttpServletResponse response) throws IOException,
UnsupportedEncodingException {
//程序以什么码表输出了，程序就一定要控制浏览器以什么码表打开
//text/html;如果写成text/html,的话浏览器会提示下载
response.setHeader("Content-type", "text/html;charset=UTF-8");
String data="中国";

ServletOutputStream out =response.getOutputStream();
//浏览器默认的字节编码是gb2312
out.write(data.getBytes("UTF-8"));
}

private void test2(HttpServletResponse response) throws IOException,
UnsupportedEncodingException {
String data="中国";

OutputStream out =response.getOutputStream();
//用html技术中meta标签模拟了一个http响应头，来控制浏览器的行为
out.write("<meta http-equiv='content-type'  content='text/html;charset=UTF-8'>".getBytes());
out.write(data.getBytes("UTF-8"));

out.write((1+"").getBytes());//这样写1才会出来
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

doGet(request,response);
}

}
